278 must someday be limited access

I know I have proposed this idea in the past with limited favor but with each day we see more evidence which convinces me of this conclusion: someday 278 will have to be a limited access highway rid of the traffic lit intersections but with on/off ramps and parallel access roads.
Todays BT has a column regarding the Catholic Church's Sunday problems and mentions the common problem is shared by the fire department. The fire department? Wouldn't it be swell if someone should lose their life because the fire department could not safely leave the firehouse!
The ways to achieve a limited access highway are varied but in a coastal region the solution almost always requires bridges up and over the cross streets. I will defer to professional traffic engineers in the final solution. Do any of you guys have suggestions or other opinions?
